Hi there, Jessica!
If you're looking for a fantastic restaurant that serves delicious African cooking with Indian flavors,
Sanaa is the place. The restaurant has beautiful views of the Sunset Savannah where you'll be able to watch gazelles, zebras, giraffes, kudu, ostriches, cranes and more as you dine.
It's so sweet of you to be concerned about your children, but please don't hesitate to include them. Children are most welcome at all restaurants at the Walt Disney World Resort with the exception of Victoria and Albert's where they must be at least ten years of age to dine. Of course, if any "fits" arise, you could always get up and walk around a little bit.
As far as the menu for Christmas Day goes, I have not seen that information available online as of yet. I recommend giving Disney Dining a call at (407) WDW-DINE, a Cast Member there may be able to provide some more insight on what types of things might be on the menu for that day.
Thanks for stopping by the Disney Parks Moms Panel, Jessica! Please let us know if we can help with any other questions you have.
Wishing you and your family a Pixie Dusted vacation!
